The measure of each exterior
Answer to Problem 10CYU
The measure of each exterior angle of a regular quadrilateral is 90.
Explanation of Solution
Given:
The given polygon is a quadrilateral.
Calculation:
The sum of the measures of exterior angles of a convex polygon, one angle at each vertex is 360.
Also, in a regular quadrilateral, there are 4 congruent interior angles.
The exterior angles of a quadrilateral are also congruent as angles supplementary to congruent angles are also congruent.
Suppose, the measure of each exterior angle be n.
Therefore,
The measure of each exterior angle of a regular quadrilateral is 90.
